Loss of torque?
HA!

There will be a slight reduction in flow velocity in the immediate junction between the turbine housing and the downpipe but in a 7000# lb. truck you'll never notice a couple HP at low RPM.

If backpressure is good, then I should be able to pop wheelies once I get around to doing the "potato stuffed in tailpipe" mod.

I'm not exactly sure about the gains from it because I know someone who did that potato mod on a guy's jeep but it still drove home the same as before...but his exhaust was ported from rust which I assume removed all of the performance gains from the potato.

He probably did it wrong!

You are suppose to hammer it in with the end of a broom handle, you have to get it in there as far as it will go for max HP.

Or maybe it was just a magical jeep, that thing blew more black smoke than half of the diesels...and it ran on 87 regular!
